​​​​​​​​​​​Age-Friendly Health Systems is an initiative of The John A. Hartford Foundation and the Institute for Healthcare Improvement (IHI) in partnership with the American Hospital Association​ (AHA) and the Catholic Health Association of the United States (CHA). As of May 2022, there are over 2800​ recognized Age-Friendly Health System participants.

Five pioneer health systems stepped forward to work with IHI to test ideas and learn what it takes to be an Age-Friendly Health System. The 4Ms Framework for Age-Friendly Care that emerged is both evidence-based and able to be put into practice reliably in health care settings.

The five Age-Friendly Health Systems Pioneers are:

• Anne Arundel Medical Center (Headquarters: Annapolis, MD)
• Ascension (Headquarters: St. Louis, MO)​
  
• Kaiser Permanente (Headquarters: Oakland, CA)
• Providence St. Joseph Health (Headquarters: Renton, WA)
• Trinity Health (Headquarters: Livonia, MI)​
